Be 1t known that VELBY POWELL, a c1ti zen of the United States ot' America, resid-V l gressively varying temperature may be provided either from hot to cold or from cold to hotat lthe option ot the operator at a rate ot variation which may be regulated to suit the preference ot the bather; and vvith these objects inl vieiv the invention consists in a construction and combination ot parts .of

which a preferred embodiment is'shown inV the accompanying drawings` uf'hereinz- Figure 1 is a side vien" of a valve embodying the invention. y

The cold and hot Water supply pipes are indicated respectively at 10 and 11 withthe valve located at the junction thereoil and consisting essentially ot a valve chamber 12 in Which is arranged the tubular valve member 13 mounted tor rotary and reciprocatory movement and having side ports 14 and 15 t'or respective registration with the inlet ports trom the supply pipes and which are shown respectively at 1G and 1T. The spray nozzle 1S which may be of any preferred construction isV arranged in communication with the valve chamber 12 and the portsot the valve member 13 are so arranged longitudinally, or in the direction of sliding or reciprocatory movement of thev said valve member, With relation to the chamber or casing ports 1G and 17 that the former may be in communication respectively with both ot the latter but not in registration therewith. TWhen one of the valve ports is in complete or full registration Wit-h one of the casing ports the other valve .port is entirely out ot communication vvith the other casing port in' any relativo position of the part-s, and When the valve member is movedlongitudinally orin the path of its axis from such extreme position to effect the opening of the other port, the exposure of the, latterWill be effected gradually until about one-halfv of thearea thereof is exposed at which time only one-halt of the first named port vvill be exposed, the exposure of the tiret-named port having been reduced*graduallyas the exposure ot the second-named port Wasine creased.` Fromthis inidWayM-positio'n the furtheri'novement of the valve in the same direction Will .involve a further increasein the exposure ofthe second-named port va nd a reduction. in' the exposure of the first-named porn-until thesecond-nained port is fully eX- posed and .the iistfnamed port is'ycompletel-y closed. `W'hile obviously this .arrangement may beaccomplished in different AWaysthe arrangement illustrated in the drawing. contemplates the disposal of the casing'ports i 16 and 17 in diametrically oppositerela` tions or in transverse registration `while the valve ports 14. and'15 are disposed in longitudinally spaced relation andat suoli a divergence longitudinally of the path, of the valve that When for example the valve port- 15 vis in complete fion and Vdirect registration with the casing port 17 the valve port. 14 is entirely out ofY communication with the casing portgl. Thereupon the downward moven'ient ot the valve member tend-V ing to open the cold Water casing port 16 will involve a g adual cutting otl'1 or closing ot' the hot water casing port 1T and' this movement respectiif'ely in opening and closing the ports Will continue until equal values or areas'ot each ot the'casing ports' 16 and 1T are exposed so that there is admitted to the casing or valve chamber equal quantities of hot and cold Water, assuming ot course that the supplies ot the Water trom thehot and cold Waterzsources areunder equal presf sures. From this midway position the turther forivard or'progressive movementfot the valve member ivill gradually closeY the casing port 17 and continue to progressively open the casing port 16 until a full opening 'of the latte-r has been reached when the eas'-` ingportl' vvill be completely closed. f y

Therefore starting with the elements of the structure as so far described in the posr kror;

tion indicated in Figure 1 ann as above described and moving the valve member gradually downward it will be obvious that the temperature ot kthe water supplied to the nozzle will first be entirely from the supply pipe 11 and hence will be hot andthe temperature will, therefore, be gradually modified or reduced until it reaches an intermediate temperature due to the mixture of equal quantities of the hot and cold water and thence will further be reduced until the supply is entirely from the cold water pipe, the hot water supply being completely cut ott.A i

The valve member 13, however, is revolubly fitted in the valve chamber or seat so that with the ports thereof in communication with both casing ports at any desired or preferred adjustment longitudinally, so als to expose to the desired relative extent the hot` and cold water casing ports so that the temperature oi the'` mixture is eXactly that desired by the operator, the volume of supply to the nozzle may be diminished by turning the valve so as to equally cut oli" or reduce the Vexposure of bo-th casing ports. This i reduction can be continued by the turning of the valve member until only a very small supply is admitted tothe valve chamber Again with the parts in the position indicated in Figure 2 wherein ythe valve member is at the'uppei."limit otits stroke'or move- `ment and lwith the valve port 15 in communication with the'casing port 17, itl will be obvious that by turning the valve member through an angular distance ot' say ninety degrees the hot water port can be entirely closed and therefore the supply ot water to the valve chamber cut otl. Again by con- Ytinuing the rotary movement of the valve member through an angular distance of ninety degrees the valve port 15 may be ai'- ranged in registration with the cold water casing port r16 and thereupon a downward movementof the valve member will cause l"a gradual closing' ot' the cold water port and the gradual opening ot the hot water port through the communication of the vvalve port la with the casing port 17, so that the ,temperature of the Water supplied to the nozzle will be gradually raised until it reaches the temperature of that in the hot water supply pipe.

In the illustrated embodiment of the invention` the valve member' is provided with a stem 19 provided at its upper end with a piston 20 operating in a cylinder 21. and pivotally connected `with the stem is a lever `22 fulcrumed at an intermediate point ot' its length in a slot 23 formed in a bracket 24 which is swiveled upon a journal 25 so that by means of the lever and by swinging the same laterally or horizontally in one direction or the other the stem may be rotated to turn or reverse the valve member 13. Pret erably the outer or free end of the lever 22 is provided with a -counterweight 26. The

longitudinal movement of the valve member i Under certa-in conditions, however, it may be desired that the gradual variationv inVv the' temperature of the water either from liot to cold or from cold to hot be accomplished mechanically or automatically, or without relying upon the manual movement or adjustment of the parts as above described, and to this end the stem 19 is madeof tubular Jform, as shown, in communication at itsk lower end with the interior of the valvechamber and in communication at its upper end with the cylinder 2l above the piston 20, and this by-pass formed by the bore ot the stem is fitted with a controlling or by.-

pass valve 27, adapted to remain closed when thev operation of the valve is to be conducted manually and provided with an operatingr handle or stein 28 whereby it may be vopened to any desired extent. supply valve member 18 in a position exposing either of the casing ports so as to admit water trom either of the supply pipes to the valve chamber, theopening ot Vthe bypass valve'will 'allow water incident to vthe pressure in the valve chamber to pass upward through the by-pass or tubular stein into the cylinder 21 and thereby'depress the lith the main `or piston 2O and consequently the main or sup- '1 Y ply valve so as to gradually advance the y later downwardly to vary the relative eir-k tentso'f opening of the casing` ports in the manner described hereinbefore in the pro- Q'ressive variation of the temperature` and this progressive movement may be utilized to modify the temperature ot' the water supplied to the nozzle by raising or lowering the temperature, according to the annular lus or rotary position of the main or supply valve or in other words according to whether the operatingl lever 22 is at one limit or the other of its horizontal path ot' movement. By varying the extent oic opening of the controlling oi" lay-pass valve,'it will be obvious that the progressive movement downwardly ot the main or supply valve may be modirlied in rate of speed from a very slow movement to one as rapid as may be desirable to the bather.

Thus, through the operation ot the tubular valve 13 it is possible to out ottq all supplv or tlowoi water. to draw either hot or iso iull head to a small stream, to draw from both sources of supply at any desired rela `tive degree of opening of the ports `to prorequired and, therefore, a conical plu-g '29, i

concentric with the main valve 1s arranged in a conical seat in the casing 30,-being held seated by spring 31, the valve chamber 12 consisting of the bore of said valve plug and the ports 16 and 17 being formed in the wall thereof and being registrable with similar ports 16a and 17a in the casing 30, so that the turning of the plug eHectually cuts off the supply. The nozzle may be carried by the plug to form a handle.

In the illustrated embodiment of the invention the bracket Q4 as above described is swiveledl upon a journal 25 which may be formed as illustrated by a tubular extension ot the valve plug 29, the bore therein serving as a means of receiving the tubular stem 19 of the piston 20, and said bracket is held in place by means of main and jamb nuts 32 and 33 threaded upon the journal while the upper end of the latter is covered by a packing cap 34 as a means of preventing leakage from the valve chamber.
